Question

well i would like to ask if nuclear fusion is used in u noe Fat man bombs that US used to bomb j*p. i noe that Little Boy is a fission bomb but im not sure if fat man is a fission or fusion bomb. Anyone answers first 10 POINTS!!

Answer 1

They were both fission bombs, the first, Little boy, was based on uranium and the second, Fat Man, used plutonium because they had no more uranium.  Hydrogen bombs (fusion) were developed later using a fission bomb as the initiator.

Answer 2

Fat Man used fusion as a start for fission. Classic.
